APC AR3100B2 42U NetShelter Server Rack Cabinet
Overview
The APC AR3100B2 is a 42U enclosed server rack cabinet engineered to house and organize standard 19-inch rack-mount IT infrastructure including servers, network switches, storage systems, and power distribution units. It is deployed by infrastructure engineers, data center technicians, and network architects in environments such as enterprise server rooms, network closets, and edge compute racks where structured equipment mounting, organized cabling, and controlled airflow are required. The enclosure provides a rigid, EIA-310 compliant platform for secure installation and long-term serviceability.
This rack supports 42U of vertical equipment space within a standardized 19-inch mounting width, enabling moderately dense rack configurations without excessive cabinet height. Adjustable front and rear mounting rails accommodate varied chassis depths, from shallow networking gear to deeper server and storage chassis. Removable side panels and full-access front/rear doors facilitate equipment installation, cable routing, and service access in structured deployments.
The enclosure includes ventilated doors and removable panels to support convective airflow, helping maintain consistent thermal pathways when integrated with room-level cooling systems or supplemental rack-level airflow accessories. Cable entry features aid segregation of power and data cabling to minimize airflow obstruction and support organized infrastructure.
Typical deployment scenarios include racks that house virtualization hosts, SAN storage arrays, aggregated network switches, and rack power distribution units. In these settings the cabinet serves as the structural foundation for efficient equipment layout, cable management, and predictable airflow within enterprise and mid-sized IT facilities.
This product is not intended for portable or temporary installations; it is designed for fixed, structured rack environments where long-term stability and serviceability are priorities.
